What Argus does.

Shadow mode first

Score and log everything without blocking. Review what would have been killed, then flip one toggle to enforce.

Sub-100ms, CPU-only

Compact classifiers baked into the image. No cold start, no GPU, inference over loopback.

OWASP Top 10 coverage

SQL injection, XSS, command injection, SSRF, path traversal, prompt injection and credential stuffing.

Fail-open by design

If Argus is unreachable or times out, the request passes through. A Kysira outage never becomes yours.

Explainable verdicts

Every decision carries a score and a plain-language reason, logged and shown in your dashboard.

Three deployment models

Standalone reverse proxy, sidecar, or Envoy external-processing filter.

See an attack die in 40 milliseconds.

Start free, run it in shadow mode, decide for yourself. The full product tour covers deployment and operations.
